Oh I have all kinds of acoustic panels, diffusers, absorbers, bass traps. Even on ceiling. You can get a good idea looking at my profile page here under Systems. Slowly but surely, my coverage percentage in my room got pretty high and satisfactory. Everything sounds AND measures (REW) very good.
Every room is different. As much as the GIK people can help remotely by seeing pictures and videos, one has to do this themselves, figure it all out by listening and measuring their room response, and get advice as the project progresses. There are no shortcuts. But the process is enjoyable, especially when the end result is good.
@bshaw :
if i had the option to hang the diffusors
Exactly which diffusers from GIK do you have? Maybe you can post a link. I don’t see how you cannot put them behind your listening chair, on the back wall. About 30-40 inches above floor level. Center.
Here is what I have on the back wall:
Combination absorption/ diffuser/ bass traps
